Specification o Letters Patent.

Patented Aug. 3, 1909.

Application filed November le, 1907. Serial No. e02,089.

State oi few York, have invented certain new and useful improvement-s in Cradles; and I do hereby declare the Jfollowing to be a full, clear, and exact description of the saine, reference being had to the accompanying drawings, forming a part of this speciand to the reterence-ninnerals marked thereon.

The present invention, which relates to cradles or supports :tor vats, tanks and the like, has for an object to provioe a construction which will support a tank upon a level or on an uneven surface.

To these and other` ends the invention consists in certain improvements and combinations and arrangements of parts that will be hereinafter more fully described, the novel features being pointed out in the claims at the end of this speciiication.

In the drawings: Figure l represents a port-ion of a vat in end elevation showing one en'ibcdin'ient ot' my invention; Fig. 2 represents a portion ot' the vat in side elevation, the base of the supporting device shown in Fig. l, being illustrated in section; Fig. 3 represents a section on line a-c Fig. 2; and Fig. t represents a portion of another embodiment of the invention, parts being shown in vertical section.

The invention is in the present instance shown as constructed for use on horizontally arranged vats or tanks l provided with annular ribs 2 formed by seams which unite the sections from which the vat is built. The vat engaging element preferably engages one ot' these ribs, as this portion of the vat is stronger than between the ribs, and therefore better able to support the weight of the vat and its contents. rhis element may comprise two members adjustably connected together, each of the members being formed of a frame 3 having a curved vat engaging tace 4 arranged at the bottom of a groove which receives the rib 2, ribs 5 extending laterally7 from opposite sides of the frame 3. The adjustment between the members may be effected by two tie rods 16 which are arranged on opposite sides of the frame and connected to the ribs 5, the latter being provided with horizontal openings through which the tie rods pass. The vat engaging element is adjustably supported on a plurality ci bases 6, one base being pro- Fixcri, g

` clement, and one or more adjusting devices vided for each member of the vat engaging preferably two, connecting each base with the vat engaging element and being rockported on the base. ln the embodinieil.- shown in Figs. l vto I5 each adjusting device comprises a depending screw 'T sei cured to one of the ribs 5 as by iitting in a socket 'therein and held against turning by an eccentric projection 8. On this screw 7 turns a nut 9 having its lower surface l() convex and resting on a concave seat formed in the base about a vertical opening ll in lthe latter, the opening l1 being tapered toward its upper end in order to permit the lateral movement ot the lower end of the screw, due to the rocking it the adjusting device. s shown in Fig. 4, the adjustable supporting devices, each comprise in addition to the screw T and nut 9, a socket piece l2 the lower convex end 12a ot' which rests in a concave seat 13 in the base 6a. vWhen two or more adjusting devices are employed for each base they should be arranged transversely of the cradle so that they will eX- tend longitudinally of the vat and in this manner prevent the cradle from tilting sidewise when for any cause there is a tendency for the vat to move longitudinally.

in operation a number of these cradles are set in parallel relation in position to receive the vat which is then lowered onto them and the members of the vat engaging element are adjusted so that the ribs lie snugly in the grooves. The supporting devices are then adjusted so that the two members of the vat engaging element lie in the same plane.

1With a cradle constructed in accordance with this invention, it is possible to provide a rigid support for vats, tanks and the like on any kind of surface, and the adjustments are such that a snug engagement ot the cradle wit-h the vat is secured.

That is claimed is:

l. n a cradle or support for vats, tanks or the like, the combination with a vat engaging element, of a plurality of bases, and a plurality of independently adjustable rigid supporting devices rockingly supported on cach base and secured to the vat engaging element.

Q. In a cradle or support Jfor vats, tanks or the like, the combination with a vat engaging element, comprising two mcnibers' having curved engaging faces, means for adjusting said members toward and from each other, of a plurality of bases, and a plurality of independently adjustable rigid supporting devices rockingly supported on each base and secured to the vat engaging l clement.

3. ln a cradle or support for vais, tanks and the like, the combination with a vat engaging element, of a plurality of bases, and a plurality of independently adjustable rigid supporting devices connecting each base and the vat engaging element and arranged in a line transverse to the cradle.

l. In a cradle or support for vats, tanks or the like, the combination with tivo frames formed with curved grooves in their upper faces, of ribs arranged on opposite sides of the frames, tie rods arranged on opposite sides of the frames and connecting the ribs on both members, pair of bases, and a pair of indepeiidently adjustable supporting devices coimecting the ribs of each member and a base.

5. ln ak cradle or support for vats, tanks or the like, the combination with two members having curved grooved faces and arranged to cooperate With the vat or tank y on opposite sides of the central vertical longitudinal plane through the said vat or tank, of a pair of independently adjustable tie rods arranged on opposite sides of and connected to both members, and indejgiendently adjustable supporting devices for said members.

6. A. cradle or support for vats, tanksl or the like, comprising two members having curved grooved faces and arranged to c0 operate with the vat or tank on opposite sides of the centrall vertical longitudinal plane through said vat or tank, and a pair of devices adjustably connecting` the members to shift them relatively to each other in a lateral direction.

T. lo a cradle or support for vats, tanks or the like, the combination With a pair of members having curved vat engaging faces and ribs arranged on opposite sides thereof, of tie rods connecting` the ribs of one member with those of the other, a pair of bases one for each member, and a pair of independently adjustable supporting devices for connect-mg each base With a vat engaging lmeinbcr and rockingly supported on its base.

8. in a cradle or support for vats, tanks or the like, the combination With tivo frames formed with grooved upper faces and arranged lio coperate with a vat or tank on opposite sides of the central vertical longitudinal plane through said vat or tank, of ribs arranged on opposite sides of the frame, tie rods arranged on opposite sides of the frame and connecting the ribs on both of said members, and a supporting device connected to each rib, the supporting devices of\ each frame being arranged in a line transverse to the cradle.
